You need to tune your gun for pellet/slug you shooting.
Did you play with power wheel, is it working correctly?
In my opinion your reg is to high, should be somewhere around 120BAR for speed you shooting and probably you will need more hammer tension.

Has anyone messed with that return setting on the FX Chrony. Or does everyone leave is on 20%

I leave mine on 20%. Yesterday, I was shooting my p-rod and not getting any readings. Then, I remembered to change the settings to pistol, and all was good. I had previously set it on the highest setting for my Daystate Wolverine HP R. I was comparing my FX to my Caldwell Precision Chrony and found that the FX had consistently slower readings than the Caldwell. Heavier pellets where narrower in their difference.
Yesterday my numbers were 40 fps difference. I was like no way it can be the gun. But I may have to play with reg or hammer spring just to see if it’s different. It seems like the heavier ammo is more consistent. Fx hybrids are to expensive lol.

What chrony were you comparing your FX chrony to?
Like I said, my FX always gave a slower reading than my Caldwell. My differences were 10-8 fps slower with the 14.36 gr pellets (avg = 8.9 fps) and 8-5 fps slower with the 25.07 gr pellets (avg = 5.9 fps).
Here's my original post:

I wasn't comparing my fx chrony to anything. That’s all I had to shoot with. I have a Caldwell but hate using that thing. The chrony was showing an ES of 40 fps. That’s what I asked if it may be the placement of the chrony or the gun not set right.
How do you have it setup when using? On your gun? Or shooting over it? If on your gun I'm gonna say definitely your guns tune is the issue more so than the chrony. Mine was very accurate with my guns. Now differences between readings on different chronys I wouldn't be too concerned with that. 2 different ways there measuring at 2 different locations so within 10-15fps is no big deal. Can't guarantee which one is more correct anyways
Don't attach anything to the barrel, do what I did https://www.airgunnation.com/topic/new-fx-radar/?view=all#post-993261 or set it on a tripod.
